HoldFast keeps a constant GPS watch on your boat and sounds a loud alarm the instant it starts to drag — even with the screen off. The core anchor alarm is free, built by sailors for sailors. SET IT. FORGET IT. SLEEP. • Drop anchor — tap your position, or offset to the exact bow location • Set your swing — adjust the watch radius from 5m to 200m • Rest easy — HoldFast keeps watch in the background while you sleep TRUSTED ANCHOR MONITORING — FREE ROCK-SOLID BACKGROUND TRACKING — An optimized GPS engine stays awake with the screen off. If your boat moves, you'll know. NO FALSE ALARMS — You set the GPS-signal-loss threshold, from 30 seconds to several minutes. No more 3 AM "ghost" alerts. PROGRESSIVE ALARMS — A gentle nudge as you near the boundary, then a loud emergency alarm if you've truly broken free. You're warned early, not too late. NIGHT-VISION DARK MODE — Keeps your cockpit dark and your night vision intact. HOLDFAST PREMIUM Unlock the extras when you're ready — choose an annual plan, or pay once for lifetime access. CUSTOM ALARM ZONES — Draw a shape around rocks, shallows, or moorings instead of a plain circle. REMOTE WATCH — Share a private live link so family or crew ashore can track your position in real time from any web browser. GPS TRACK HISTORY — Replay exactly how your boat swung through the night on a colour-coded track. CUSTOM ALARM TONES — Choose a piercing tone that's guaranteed to wake you. PRIVATE BY DESIGN No account to create. No data collection. No internet required for core alarm functions — the watch runs entirely on your device. Download HoldFast and take the stress out of the anchorage.
